Finishing the Greenhouse

Once the frame was built, it was covered with 6 mil plastic. Wood blocks were screwed into each corner to anchor the plastic and stretch it over the curved top of the greenhouse. The ends were fan folded and a wood block was used to anchor the ends of the plastic. I left enough room below the wood blocks to be able to access the end of the greenhouse for watering or adjusting of the heaters.


500 watt Optimus H-6002 mini oil heaters were added to each enclosure to keep the trees warm when the temperature drops below 20 deg F. The heaters are plugged into Thermo Cubes.









The Thermo Cube provides power when the temperature drops below 35 degrees F. I added a string of red Christmas lights so that I could see when the power was on and off. The heaters also have built-in thermostats. When the temperature outside dropped to 20 Deg F, I adjusted the heater thermostats on.
